Abstract: 785,747. Making hose reinforcements. TITEFLEX, Inc. March 14, 1956, No. 8046/56. Class 83 (2). [Also in Group XXVIII] A reinforcing member for a flexible hose (see Group XXVIII) is made by providing transverse slits 25, Fig. 6, in a ribbon 24 of metal to form cross-bands 26 interconnecting the edge portions 27 of the ribbon, and then pressing alternate cross-bands outwardly from the plane of the ribbon and in one direction while the intervening cross-bands are simultaneously pressed outwardly in the opposite direction.

Title: Improvements in and relating to tobacco leaf forwarding and controlling mechanism, particularly for tobacco leaf stemming machines
IPC: A24B5/12
Filed: 1935-03-15
Abstract: 441,588. Tobacco-stemming machines. INTERNATIONAL CIGAR MACHINERY CO., 5520, 2nd Avenue, Brooklyn, New York, U.S.A. March 15, 1935, No. 8067. Convention date, Oct. 17, 1934. [Class 130] A roller coacts directly with tobacco leaves forwarded in succession to detect unstemmed or partly stemmed leaves and to control the operation of mechanism which separates the faulty leaves from the others. Tobacco leaves emerging from a stemming machine are fed by a belt 13 beneath a detector roller 11, on to the lower run of a perforated conveyer belt 44 on which they are held by suction maintained in chambers 46a, 46b. With a stemmed leaf in the position Lc a cam 24 permits a lever 21 to be moved by a spring to close a valve 33 and cut off the suction in the chamber 46b; simultaneously a disc valve 29 is opened by the lever 21 to admit air into the chamber. The stemmed leaf falls from the belt 44 on to a transverse conveyer TC, and its transference is expedited by lowering a plate 47 in the chamber 46b to expel the air through the perforations in the belt. The plate 47 is lowered, after the actuation of the valves 29, 33, by a spring 57 which maintains a roller 53 in contact with a cam 62. An unstemmed leaf on the belt 13 raises the detector roller 11 and shifts a lever 12 to close contacts 14 in the circuit of a relay 81, Fig. 8, which closes a switch 80 and energizes a solenoid 15. The core 16 of the solenoid 15, through a link 17, swings a bell crank lever 18, having an arcuate head 18a, into a vertical position where it displaces axially one of three pins 20 on a gear wheel 19, into the path of movement of an arm 21c on the lever 21 to prevent the spring operating the valves 29, 33 and cutting off the suction in the chamber 46b. The suction holds the plate 47 against the pressure of the spring 57 and an unstemmed leaf Ld is carried to the end of the belt 44 and deposited in a trough T. As the gear wheel 19 rotates a stationary cam returns the displaced pin 20 to its normal position.

Title: A device for burning atomized liquid fuel

Filed: 1934-03-14
Abstract: 419,852. Liquid-fuel burners. BARGEBOER, A., 112, Oude Scheveningsche Weg, The Hague. March 14, 1934, No. 8096. Convention date, March 14, 1933. [Class 75 (i).] In a liquid-fuel burner in which the fuel is sprayed by a pressure atomizer 8, a regulable quantity of the air supplied for combustion by a fan 2 through a pipe 6 is conducted through a pipe 7 having a conical end 21 directing the air inwardly towards the axis of the atomizer. In the construction shown the air enters the pipe 7 past an adjustable valve 14 arranged in front of screw blades 25 which impose a resistance on the main air current but the pipe 7 may alternatively be connected to the main air pipe in front of the throttle valve 4. The atomizer 8 may be surrounded by a cone 30 and helical blades 20, and is carried by fuel flow and return pipes 10, 11 mounted in a cylinder 13 which is adjustable angularly and axially in the end cover 17 of the pipe 6. The cover 17 also carries the supports 16 of the pipe 7 and a screw 28 for adjusting the valve 14. The angle at the apex of the cone 21 is preferably greater than 60‹. Ignition is effected by electrodes 24 supplied from a transformer 26. In large burners the cone 30 may be formed with helical blades and the pipe 7 may be adjustable relatively to the pipe 6.

Title: Improvements in or relating to pulse receivers
IPC: G01S7/292
Filed: 1957-03-12
Abstract: 818,349. Radio receiving systems; pulse radar. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 12, 1957 [March 28, 1956], No. 8097/57. Classes 40 (5) and 40 (7). In an arrangement for reducing the effects of interference in a receiver for pulses of highfrequency waves, e.g. a radar receiver, the receiver comprises two channels with their inputs fed with received pulses, one of the channels comprising a phase detector to which reference oscillations of the frequency of the waves in the input pulses are also fed, and the other channel containing an amplitude detector, the outputs of the two channels being combined to supply signals for utilization. As shown, the output of the intermediate frequency amplifier 6 is fed to two channels, one channel including a limiter 7, phase detector 8 with its reference oscillator 9 supplying a local oscillation of the same frequency as that of the incoming pulses and in a fixed phase relation with the desired signal, and a full-wave rectifier 10, and the other channel comprising an amplitude detector 11. The outputs of the two channels are combined at 12 and the overall gains in the two channels are such that the noise levels are substantially equal at the input to the combining circuit 12. It is stated that an improvement in the signal/noise ratio by a factor of #2 is obtained, the desired signals in the two channels, which are coherent, being combined additively, and the random noise outputs from the two channels being combined in quadrature.

Title: Modification of the properties of filaments, bristles, yarns, films and like shaped articles derived from nylon
IPC: D06M13/127
Filed: 1944-05-15
Abstract: Undrawn filaments, bristles, yarns, films and like shaped articles derived from nylon are treated with formaldehyde or an organic diisocyanate to form cross-linkages, and are then heated under substantially anhydrous conditions in the presence of an alcohol, formaldehyde and a catalyst until the nylon contains at least 4 per cent of combined formaldehyde based on the weight of the nylon.  The catalyst is an acid with ionization constant of not less than 1.0 x 10-2 at 25 DEG  C. or the ammonium salt of such acid, alone or in admixture with acids or salts with lower ionization constants. Examples of suitable catalysts are sulphuric acid, hydrochloric acid, phosphoric acid, oxalic acid, p-toluene sulphonic acid and trichloracetic acid.  The cross-linkages may be formed by means of formaldehyde in the manner described in Specifications 534,698 and 565,066, or by heating the articles in the presence of an organic di-isocyanate such as ethylene di-isocyanate, trimethylene di-isocyanate, tetramethylene di-isocyanate, hexamethylene di-isocyanate, decamethylene di-isocyanate, m-phenylene di-isocyanate, naphthalene di-isocyanates and adipyl di-isocyanates. The treatment is continued until the article does not dissolve when immersed in m-cresol and raised to the boiling point thereof.  The following alcohols are specified as suitable for use in the second step in the process, methyl alcohol, ethyl alcohol, n-propyl alcohol, n-butyl alcohol, iso-butyl alcohol, octyl alcohol, dodecyl alcohol, methallyl alcohol, glycollic acid, castor oil fatty acids, cyclohexanol, ethylene glycol, diethylene glycol, b b 1-dihydroxydiethyl sulphide, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether and benzyl alcohol.  The reagents may be dissolved in a liquid which has no solvent action on the nylon, for example, the alcohols themselves, or mixtures of alcohols with ethylene dichloride, dioxan or chlorobenzene. The following examples are given.  (1) Undrawn polyhexamethylene adipamide yarn is heated in formalin in the presence of ammonium chloride, removed, baked, and then heated in a solution of methanol, formaldehyde and oxalic acid. After fully extending by cold drawing the yarn has a recoverable extensibility of 140 per cent of its length.  (2) Undrawn polyhexamethylene adipamide yarn is heated firstly in formalin containing oxalic acid and then in methanol and formaldehyde as in the previous example.  (3) Undrawn polyhexamethylene adipamide yarn is heated with hexamethylene di-isocyanate and then reacted with methanol and formaldehyde as in the first example.  (4) Undrawn polyhexamethylene adipamide yarn is heated in formalin containing b b 1-dihydroxydiethyl sulphide and ammonium chloride, and then reacted with methanol and formaldehyde as in the first example. Specifications 461,236 461,237, 474,999, 495,790 and 582,517 also are referred to.
